Some answers, to the best of my knowledge:
"Money received, or paid on your behalf (e.g., bills), not reported elsewhere on this form"
Does this include tuition my parents paid? Do I need to declare the money my parents gave me for rent?
This definitely includes the rent your parents paid, and probably includes tuition, unless the ask about tuition elsewhere on the form.
For school codes
I don't know which schools I've been admitted to yet, so should I just list every school I applied to regardless of my status?
There are only 10 spots on the FAFSA, is there anyway to add another 5 schools somehow?
You'll have to submit a second (identical) FAFSA for the 5 more schools.
So, does everyone applying for law school apply as an independent on their FAFSA? One of the prereqs for independent status is entering graduate school in 2008, so wouldn't everyone get that?
Yes, you get to apply as an independent, because you're a law school applicant.
Hope this helps...
